[0040] In the description of the present disclosure, it needs to be illustrated that, except as otherwise noted, the terms such as install”, “link” and “connect” should be generally understood, for example, the components can be fixedly connected, and also can be detachably connected or integrally connected; the components can be mechanically connected, and also can be electrically connected; the components can be directly connected and also can be indirectly connected through an intermediate, and two components can be communicated internally. For those skilled in the art, the specific meanings of the terms in the present disclosure can be understood according to specific conditions.Embodiment 1
[0041] Referring to FIG. 1 to FIG. 7, the embodiment provides a heating and thermal insulation apparatus. The heating and thermal insulation apparatus includes a power supply component 2 and a heating wire 1 electrically connected to the power supply component 2. The heating and thermal insulation apparatus further includes a heating body 3. The heating body 3 includes a heating contact surface 31 located at the top and a placement surface 32 located at the bottom. A heat source layer 33 is formed between the heating contact surface 31 and the placement surface 32. A working part 11 of the heating wire 1 is located on the heat source layer and is tightly wrapped by the heat source layer 33.
[0042] In the embodiment, the heat source layer 33 is an elastic pouring layer. For example, the heat source layer 33 may be silicone rubber, PE, TPE, or PLA, and is silicone rubber in the embodiment. By pouring silicone rubber in the heating wire 1, the heating wire 1 in the elastic pouring layer is in close contact with the silicone rubber part, so that a situation of position offset is not prone to occur.
[0043] The heating contact surface 31, the placement surface 32 and the heat source layer are at least made of a flexible material. As a preferred solution rather than a limitation, all materials of the heating body 3 in the embodiment are flexible materials, where the heating wire 1 includes an electric wire and an insulation material that wraps the electric wire.
[0044] In the embodiment, the heating and thermal insulation apparatus includes a flexible top plate 34. The heating contact surface 31 is formed on an upper surface of the flexible top plate 34. The heat source layer 33 is located below the flexible top plate 34. The placement surface 32 is formed at the bottom of the heat source layer 33. Specifically, the heat source layer 33 in the embodiment may be used as a flexible bottom plate of the heating and thermal insulation apparatus.
[0045] As a preferred solution rather than a limitation, the flexible top plate 34 in the embodiment includes an annular outer wall 341 corresponding to a contour of the heat source layer 33, and the annular outer wall 341 is sleeved on a periphery of the heat source layer 33. Thus, the periphery of the heat source layer 33 as the flexible bottom plate is wrapped by the annular outer wall 341. The flexible top plate 34 in the embodiment is integrally formed, so the heating and thermal insulation apparatus in the embodiment is higher in structural stability. In addition, when the heating and thermal insulation apparatus in the embodiment is placed on a table in a forward direction, from a perspective of a user, only the flexible top plate 34 is exposed out of the heating body 3 as a whole, thereby improving an integrated effect of the heating and thermal insulation apparatus in the embodiment of the present disclosure, and improving using experience of the user. The flexible top plate 34 is made of silica gel, PE, TPE or PLA.
[0046] As a specific solution rather than a limitation, the placement surface 32 includes a placement surface body 321 located at the bottom of the heating body 3, and a plurality of support bulges 322 protruding downward from the placement surface body 321. A heat dissipation channel is formed between the support bulges 322. In the embodiment, the heating body 3 is raised by the support bulge 322, so that a heat dissipation channel is formed between the support bulge 322 below the heating body 3, thereby facilitating heat dissipation at the bottom of the heating and thermal insulation apparatus and improving product stability.
[0047] In some embodiments, the support bulge 322 and the bulge body 3 may be integrally formed and made of a same material. For example, the support bulge 322 may be a U-shaped stand column. Preferably, in the embodiment, the support bulge 322 includes a bulge body 3221, and further includes a support transition part 3222 extending slantly and upward from the bottom of the bulge body 3221. The top of the support transition part 3222 extends to the placement surface body 321.
[0048] Further, the bulge body 3221 has an elliptical cross-section shape. A shape of the support transition part 3222 corresponds to that of the bulge body 3221. The support transition part includes a long end 3222a corresponding to a long axis of the elliptical bulge body 3221, and further includes a short end 3222b corresponding to a short axis of the elliptical bulge body 3221. The support transition part 3222 in the embodiment increases a contact area between the support bulge 322 and the placement surface body 321, so that the support bulge 322 may have a good effect of supporting the heating body 3. When a to-be-heated object is placed on the heating body 3, a situation of deformation or collapse caused by the fact that there is a lack of support at a partial position of the heating body 3 cannot occur, thereby improving product stability.
[0049] The to-be-heated object in the embodiment includes, but is not limited to, a meal, tea, and food ingredients. For example, the heating and thermal insulation apparatus in the embodiment may be further configured to dry clothes, thaw food ingredients, heat a facial mask, and the like.
[0050] As a specific solution rather than a limitation, the heating and thermal insulation apparatus includes an insulation housing 4 configured to place the power supply component 2. A leg 41 is formed at the bottom of the insulation housing 4. The bottom of the leg 41 and the bottom of the bulge body 3221 are located on a same horizontal plane. The bottom of the leg 41 and the bottom of the bulge body 3221 are located on the same horizontal plane, so that the insulation housing 4 is effectively supported, and the structural stability of the heating and thermal insulation apparatus is further improved.
[0051] As a specific solution rather than a limitation, the heating wire 1 further includes a connecting part 12 extending from the heat source layer 33 to the power supply component 2. The connecting part 12 includes a first end 121 and a second end 122. A working part 11 of the heating wire includes a line-shaped section 111 and a U-shaped circuiting section 112 that are connected. The line-shaped section 111 is connected to the first end 121 of the connecting part 12, and the U-shaped circuiting section 112 is connected to the second end 122 of the connecting part 12.
[0052] As a specific solution rather than a limitation, the heating body 3 has a thickness of smaller than 5 cm, and a laying area of the working part 11 of the heating wire 1 is greater than 60% of a surface area of the heating body 3. Preferably, the thickness of the heating body 3 in the embodiment is a sum of a thickness of the flexible top plate 34 and a thickness of the placement surface 32. The heating body 3 has a thickness of about 2-3 cm. The paving area of the working part 11 of the heating wire 1 is greater than 80% of the surface area of the heating body 3.
[0053] As a specific solution rather than a limitation, the insulation housing 4 includes an upper housing 42 and a lower housing 43, and an opening 44 into that a side edge of the heating body 3 stretches is formed between the upper housing 42 and the lower housing 43. The insulation housing 4 is disposed at a short side of the heating body 3, and the short side of the heating body 3 stretches into the opening 44. By providing the short side of the opening 44 to stretch into the heating body 3, a combination of the heating body 3 and the insulation housing 4 is closer while a good integrated effect is ensured.
[0054] In the embodiment, a notch 35 is formed at the short side, and the first end 121 and the second end 122 of the connecting part 12 stretch out of the notch 35 and enter into the insulation housing 4 to be electrically connected to the power supply component 2.
[0055] In order to further strengthen the structural stability of the heating and thermal insulation apparatus, a plurality of first through holes 36 are formed in an edge that is of the heating body 3 and that corresponds to the notch 35. Positioning columns 421 are formed at corresponding positions of the first through holes 36 in the upper housing 42. Second through holes 431 are formed at corresponding positions of the positioning columns 422 in the lower housing 43.
[0056] A heat-sensitive color change layer is further disposed on a surface of the heating contact surface. The user may intuitively observe a pattern range and a depth of the heat-sensitive color change layer, which determines a temperature and a radiation range of the heating body 3, and provides an intuitive indication for the user to perform a heating / thermal insulation operation.
[0057] As a preferred solution rather than a limitation, the power supply component 2 in the embodiment further includes a control module. The control module is configured to control a temperature gear of the heating body 3 and provide a timing switch function.
